In this example, ports 22 and 3389 are opened to allow inbound traffic from a source IP address using SSH and RDP respectively.

For testing purposes, you can specify a Custom IP address of 0.0.0.0/0 to enable all IP addresses to access your instance using SSH or RDP. Note that this should only be done for brief periods in test environments. In a production environment, only a specific IP address or range of addresses should be allowed to access your instance.
